Pretty much. My engine doesn't need huge high voltage wires (yet) nor a real hot coil, although I'm thinking that the lack of a ballast and the improvement the GM module gives in switching adds some. I no longer have access to equipment that can truely measure spark ENERGY. Voltage does not tell the "whole story."

There seems to be disagreement on the www about whether you can run a stock coil with one of these. I actually have three systems -- the Cletrac, the Dart, and the "emergency" system I built which I ran on the Dart for over an hour mostly to test reliability of the unknown condition of the coil, and coil heating.

This thing has already come in "pretty damn handy" for test firing two used engines
